Recognise a contagious fungal infection causing scale and patches of broken hair.
Editorial publication · Medical review pending.
Understand
Tinea capitis is an infection of scalp hair and skin caused by dermatophyte fungi.
Possible symptoms
Itchy scaly patches with broken or missing hairs can appear; a highly inflamed form produces a painful boggy swelling called a kerion.
Causes and associated factors
Infection spreads through contact with an infected person or animal or contaminated items such as combs, hats, towels or bedding.
Diagnosis
Scalp examination is supported by samples of hair or scale to identify the fungus before or during treatment.
Tests
Microscopy and fungal culture confirm infection; a special lamp can help with some species but is not sufficient alone.
Course of the condition
With appropriate treatment, infection usually clears; severe kerion or delayed treatment can leave scarring loss.
Care options
Scalp ringworm usually needs prescribed oral antifungal treatment; shampoo and hygiene measures reduce transmission but do not replace systemic treatment.
When to consult
Seek medical care for any suspected scalp ringworm, especially in a child, and avoid sharing objects that touch the hair.
Urgent help
A very painful boggy swelling, pus, fever, major swelling or a very unwell child needs urgent assessment.
